DIY Signal Generation

12

Create a Signal Source for a Variety of RF Applications

Neal describes how he built an inexpensive and accurate variable-frequency signal generator on a two-sided PCB. The system delivers frequencies from 0 to 3 GHz with a frequency accuracy of less than 200 Hz.

SILICON UPDATE - Hot Enough for You?

78

As Tom explains, having all the MIPS and megahertz in the world means nothing unless your design has some meaningful real-world data to process. To gather such meaningful data, you need innovative sensors. This month, Tom introduces a handy option you should consider for your next temperature-sensing design—an infrared noncontact IC thermometer.
